You can't do anything in beta. Battery drain is a major issue as it's a beta version . And if u are running your primary device in beta it's better to rollback to andriod 11. I was also in beta but battery was draining a lot. Like a fullcharge was just going for 6-7 hours with the least minimal usage( 30 min of youtube , 30 minutes of call, and 35 min of music playback). So if you're running your primary device in beta it's better to wait for stable version. And before roll back do remember your phone will get formatted during downgrade and some of the backup won't work like home screen setting and device setting.
